The object of ythe invention isto' provide improvements in combinedvalves and .miick ing devices, particularly for-such purposes as thoseV metwith in the use of syringe.s,disin` yf'ectfnfitfand spraying apparatus. j

In this class of apparatus it has long been `customary to prepare a mixture' of antiseptics, disinfectants andthe likein avesse/land to'lead `the fixed mixture from the vessel tothe desired point of application Without substantial alteration, and controlled at most only byfa suitable Valve." However,y there yare, many' instances when fluids of different na'ture'for strength are'desired selectively,

such Vfor Vexample asl lthe use of clear Water first, followed bythe usefof van antiseptic, or disinfectant, and vice versa, as inmedical practice.4 [Alsovv in "the ,spraying of trees, plants, vines and the like, 1t has long been.r

recognized that itj'vvpuld'be. desirable" inmany instances to Vswitch at will from a'fcliemical ,designed to f kill sap-'sucking insectsftofonef which is effective againstleaf-'eating insects`, v

suitable forni of faucet connectlngmeans 9.

' Without: irstrhavingy torv remove thek 'former preparation from thef'buclet, tank "or otherr reservoir, before being able'to' inserttherein and make use of the latter. v

The, object thereforel has been to provide a casing, Which embodies in addition to a suitable valve, a simple arrangement for mixing a given substance with a fluid passing therethrough, comprising a chamber havinginlet and outlet portsand in which is slidably positioned a second container adapted to Vcontain either a liquid or asoluble solid, said secondy container when in Withdrawnv position being yremoved fromv the direct How of liquid through the first container, but When in normal operativeposition said second-containerbeing so placed that fluid passing'into and through said v'first container also" passes through inlet and outlet apertures in the second container, and thereby gains access to the contents of thelatter Which yare gradually carried off by the fiuid'inaprelatively Weak solution.

Withthese and other-objects vmind the 5 present invention comprises furthervrdet'ails of constructionk and operation which are fully brought out the following descriptionw` vvhen read in conjunction Withthe accom- `vpanying dravvin gs, in ,Which Fig. 1 is a'partial side.v elevational and Vertical,1 longitudinal s ectlonalvievv of one embodimentof the yin- .y vention in association With any Well-known 'form' ofltubes,'nozzle and faucet Aattaching means; Fig. 2 is asimilar section lofv the'devvice perxsevvith the inner container inwithdrawn'posit-ion; andrlig;` 3' is an enlarged 'fragmentary-diametrical section ofthe l'lovve 16.0" er portion of the .device shown in AFig.`2 and `at'rightfi'angles With the vplane thereof.

Referring to the drawings,l theinvention pri'marilycomprises a container 1', havinga tubular bore i12, provided Withl radial-.exten- 'lsions Sande: provided respectively With inlet andioutletraperturesv 34 'and 4J.' To'the. eX-

tension 3 ispreferably integrally connected "6,3 and itself provided With` an extension ;7,to which is secured one end ofa flexible tube'8,'f

To' the'y second lcontainer extension'il4 is also g secured one end of aflex'ible tube 10, which,

l provided vvith a fluid sealing Washer-15,While a valve casing 5', containingv any suitableform of valve having ai manually '.engageable knob a7o the opposite endof which is attached to any y knna'lly threadedxplug 14;, which isfpreferably beneath the "head 13 the cylinder12r1is pro-VY i videdfwith screw threads 16, adapted when v the cylinder is in its' inner-.most position. to engagey corresponding threads lWithin-)the l boreQ, .to maintain said vcasing Yand cylinder` yirl-'normal operative position; a kWasher 17 'being provided, yifl desirabl e",1yto prevent t the escape of fluid outvvardly'through said bore f between the walls ofthe container and cylinder.

The'b'o're V2 in the lower portion of thereon.-A

`tain'er 1 is radially enlargedto providerajj chamber 18, finto' and fromA Which; lead.V the inletl and ""outletbores f 3c and 1f respectively.

They lovvernost portion .j y19 of said.. container ,y

s "Y Y is externally threaded to receive a detachable cap 20, which is provided inwardly with a gasket 21, which binds against the lower portion of the container to effect a seal to prevent the -escape ot fluid thereby.

The lower portion of the cylinder 12, which in eiiect comprises an inner container, is provided with as many relatively restricted inlet and outlet apertures 22 and 23, as may be desired, the bottom of said cylinder being closed by a wall 24 into which extends a small bolt or screw 25, which secures to said wall a gasket 26.` which is of Vslightly greater diameter than said cylinder, but is of less diameter than the enlarged portion 18 of the container bore 25 and which is securedin position by means oic a preferably metallic plate 27, said plate and .gasket beingg` normally prevented from relative rotation by means ot a pin, or the like, 28 which extends through them and into the bottom wall 24e-oi the cylinder 12.

The cylinder or inner container 12 may be filled to the desired extent with anysuitable solution or soluble solid. such for instance as potassium perma-nrranate, after'which the plug '14e is replaced, as shown in the drawings. said plut; beine; preferably connected loosely with the container 1 by means of a flexible chain or the like 29, to` prevent accidental. separation therefrom and possible loss. When said cylinder is in its lowermost and normally operative-position, as shown in Fin: 1. and the valvebeing turned so as to permit water or other fluid to flow through the tubes 8 and 10. said fluid passes inwardly through the inlet bore 3. into the bore enlarrrement 18 and outwardly through the out let bore lsome of such fluid having passed into the interior of the cylinder 12 through theapertures 22. where it dilutes and assimilates with the chemical 30. carrying a por tion of such chemical outwardly through the apertures 23 to ioin other ot such fluidvvhich has passed circumferentially around the .outer'surface of said cylinder.

It is obvious that manipulation of the valve 6 regulates the iiow ot the `fluid from the nozzle 11 from Zero to maximum capacity ot the channel passino throuojh the device, and an'v rates of tlow between these two extremes. However, when it is desired to permit onlv clear water or other iiuid to nass through said Y tubes and from said nozzle. the cvlinder head 13 is rotated so as to disengrae'e the retaining threads 16 and permit the c vliu der to be withdrawn lon .Qitudin ally into. anddn fa ct slight- .lv above. the positionsh awnr in Fi 2. In this latter position it will benoted that the in let and outlet apertures ot the cylinder are closed and th clear fluid flowing inwardly through the inletbore 3 passes around the loose vfitting gasket 26V and freely through 'the outlet bore 4l. The gasket it will be noted aii'ords a means for limiting the relatively up? Havingthus described my invention, what I claim and desire to protect by Letters Patn ent of the United States is f i mixing device, comprising an outer coneral shoulder beyond which there is an enlargement of said bore into which lead inlet and outlet ports, a second container reciproeable lonyitudinally within said bore and having inlet and outlet apertures which in one relative position of said containers com.- municate with said'ports, and when said containers arein another relative position the apertures of said second container being closed within and by the slidably contacting Wall` of said bore, and a gasket larger than said bor-e carried by said inner container and when in cooperation with said shoulder being operative to both limit the relative movement ot said containers in onel direction and to maint-ain. said apertures closed bypreventing them from emerging from and beyond the surrounding' wall of said first container, and to prevent Huid escaping troinwithin said bore enlargement past said shoulder and said innercontainer.
